Abstract: A workbench comprises a work surface disposed on a supporting structure.   The work surface comprises a vice jaw member carrying a first vice jaw and a worktable having a second complimentary vice jaw. The worktable, in a working position thereof, lies in the same plane as the jaw member, and the jaws face one another and are adapted to be moved towards and away from one another by vice operating means. The worktable is pivotally mounted with respect to the supporting structure about an axis lying adjacent the back edge of the worktable, thereby enabling the worktable to be pivoted away from the supporting structure to give access to the underside of the worktable. The underside is provided with means for mounting at least one power tool thereon. and has several tool apertures through which working parts of the power tools can project to the upper side of the worktable for working on a workpiece presented to it when the worktable is returned to the working position.  The vice operating means enables asymmetric separation between the vice jaws.

Title: Propylene carbonate recovery process
Inventor: BANTU NAGESHWER RAO
IPC: H01L21/30
Filed: 1993-04-20
Granted: 1997-04-08
Abstract: Disclosed is a method of recovering a cyclic alkylene carbonate, such as propylene carbonate, from an effluent stream of a process in which the cyclic alkylene carbonate removes an organic photoresist material from a substrate. The effluent is a cyclic alkylene carbonate effluent, e.g., a propylene carbonate effluent, of the carbonate, water, and polymeric solids. In the recovery process the cyclic alkylene carbonate effluent is fed to a heat exchanger, and separated into (i) water and volatiles, and (ii) cyclic carbonate. This lowers the concentration of water in the cyclic alkylene carbonate to a level that is low enough to substantially avoid hydrolysis of cyclic alkylene carbonate to the corresponding glycol. The dewatered cyclic alkylene carbonate is evaporated to separate the cyclic alkylene carbonate from high boiling materials and polymeric solids. The dewatered cyclic alkylene carbonate is separated into (i) a cyclic alkylene carbonate fraction, and (ii) a photoresist solids fraction. The photoresist materials fractions contains photoresist material in the alkylene carbonate. The cyclic alkylene carbonate fraction is further separated in a fractionation means into a higher vapor pressure alkylene glycol fraction, and a lower vapor pressure alkylene carbonate fraction.

Abstract: An MWD measuring apparatus and technique using a single transducer mounted on an MWD drill collar near a tubular member, such as an upset or stabilizer blade.      The minimum stand-off is the radial difference between the MWD drill collar and the tubular member when the drillstring is side-walled against the borehole wall.      Control apparatus connected to the transducer determines elapsed time for each pulse transmitted towards and reflected from the borehole wall. A plurality of round-trip transit time (RTT) values are measured and the results statistically analyzed to identify and verify the RTT min value corresponding to the minimum stand-off distance. The RTT values may be analyzed directly or using histogram techniques. Once determined, the sound speed of the drilling fluid is calculated as twice the radial difference between the MWD collar and stabilizer blade or upset divided by the RTT min value. Also, the sound speed is used to calculate the stand-off distance corresponding to other RTT values, if desired.

Abstract: A refrigeration system of the type having an economizer cycle is provided with a null cycle, in addition to heating and cooling cycles, without shutting a compres-sor prime mover down, to preserve air flow in a conditioned space. First, second and third controllable valves respec-tively: (1) select main and auxiliary condensers, (2) open and close a liquid line, and (3) open and close a line which provides a warm liquid to an economizer heat exchang-er. The valves are controlled in at least one predeter-mined open/close pattern during a null cycle, and prefera-bly in a plurality of selectable predetermined open/close patterns, to provide a null cycle at any instant which sub-stantially matches the net heat gain or loss taking place in the conditioned space. Thus, the temperature of the served space will be more apt to remain in a null tempera-ture range close to set point, providing smoother and more accurate control over the temperature of the conditioned space for longer shelf life of perishables stored therein.      The system achieves the latter by controlling maximum operating pressure.
